Y

In Figs. 6, 7, 8 and 9 the fluted periphery of the hollow cylinder 24 isprovided with grooves 25 adapted` to receive individual teeth 26 thatare conformed on their inner sides to the groove and may be of anypredetermined' form adapted to the operation of they plaiting on theirouter sides. In the form shown the inner sides 27 of the lteeth aresemi-circular-and the outer faces 'are flat from end to end thus formingon each of the rollers toothed surfaces corresponding tothatindicated-inV Fig. 6. The individual teeth 26 are held in their seatsrespectively by connectors 28 which are fixed in projecting lugs y29 ofthe individual bar-like teeth 26 that extend from end to end of thecylinder.

Said connectors are also provided with the eyes 30 fastened by screws 31to the head 32 of the hollow cylinder. The connectors 28 may be fixed tothe lugs 29 by any suitable means and are shown as being rivetedthereto. In Figs. 8 and 9, the connectors are represented as helicalsprings 33 fixed to projections 29 ofthe teeth, and connected by screws34 to retainers 35 that are fixed to the head 32.

The base 36 of the frame is provided with two rigid uprights 37, 38. Theupright 37 is provided at'its upper end with a stationary bearing 39',and said uprights 37, 38 are provided with co-axial stationary bearings39, 40 to receive the co-axial stub shaft 4l, and the hollow shaft 9 ofthe lower cylinder 2. The upright 38 is provided with anupwardlyprojecting arm 42 which has a support 43 that may be a hollow'bearing onwhich is mounted the oscillating bracket 44- having the radial arms 5and 6 provided at its ends with the journal which I mount the shafts Yofthe upper cylinv der provided with teeth meshingowith the teeth of thelower cylinder.

The spring 8 operates upon the oscillator to depress the roller towardand into contact with the corrugated Vor fluted periphery of the roller2. By the construction shown the i fluting iron or upper roller 3 may beswung Vup away from the lower vroller 2 and the material to be plaitedis inserted over the lower roller and the upper roller allowed to bebrought into position shown in Flg. l,

l and the rollers heated by steam are revolved by power applied to thepulleyl4, and the material is quickly plaited to the form produced inthe well known manner.

By mounting the upper roller 3 on the radial arms 5, 6, and pivotingsuch arms at the cylinder,

bearings 45, 46 in said one end as shown in Fig. 2 provision is madewhereby only a portion of a piece of fabric may be'plaited if desired,i. e., "if only one edge of a piece of fabric is to be plaited suchfabric may be inserted rollers to the depth to which the fabric is to beplaited and then run through the device, and that portion of the fabricthat is not to be plaited may freely extend out of one end of therollers without interference by the roller supporting means at suchend.I claim. A l

1. A plaiting machineA comprising two toothed rollers adapted to meshwith each other, and to crimp `into plaits a fabric run between them;one of said rollers being stationed on asupport; and a radius armoscillatable on said support; the second of said rollers being journaledto said radius arm and adapted to yieldingly press a fabric toward thestationed roller.

2. A plaiting machine comprising uprights; a toothed roller mounted insaid uprights; an oscillating bracket hinged to one of said uprights;and a toothed roller journaled in said bracket and adapted to cooperatewith the other roller for the purpose set forth. l

3. A plaiting machine comprising a hollow cylinder, a cap for one end ofsaid cylinder; means to introduce steam into the cylinder; a `toothedshell to fit said cylinder, and meansrto fasten said shell on thecylinder.

4. A plaiting machine comprising in combination, a hollow cylinder openat one end and closed at the other end, of a cap threaded tothe open endof the cylinder and provided with a steam pipe; a toothed shell lmountedon the cylinder and abutting against the cap, and means for securing theother end of the shell against removal from said cylinder being adaptedto revolve and to meshV with the corresponding cylinder. f

'5. In a plaiting machine the combination with a cylinder of 'a toothedshell for said cylinder; a stop for s'aid shell at one end of cylinderand 'a screw screwedV into the other end of the cylinder and having aneccentric projection to retainthe YVshell kon ythe cylinder. f Y 6. Aplaiting machine comprising. two toothed rollers adapted to meshv witheach other and to crimp a fabric run between them; a stationary supporton which one of said rollers is journaled, and a radius arm oscillatableon the stationary support; the second roller beingl journaled thereon;and means to revolve one of said rollers.

In testimony whereof, I have hereunto set my hand at `Los Angeles,California, this 26th day of September, 1921.V f
